###### 4. Formal Logic / B. Propositional Logic PL / 2. Tools of Propositional Logic / c. Derivation rules of PL
 14273 Conditional Proof is only valid if we accept the truth-functional reading of 'if'
###### 10. Modality / B. Possibility / 6. Probability
 14281 A thing works like formal probability if all the options sum to 100%
 14284 Conclusion improbability can't exceed summed premise improbability in valid arguments
###### 10. Modality / B. Possibility / 8. Conditionals / b. Types of conditional
 14270 Simple indicatives about past, present or future do seem to form a single semantic kind
 14269 Maybe forward-looking indicatives are best classed with the subjunctives
###### 10. Modality / B. Possibility / 8. Conditionals / c. Truth-function conditionals
 14275 Truth-function problems don't show up in mathematics
 14274 Inferring conditionals from disjunctions or negated conjunctions gives support to truth-functionalism
 14276 The truth-functional view makes conditionals with unlikely antecedents likely to be true
 14290 Doctor:'If patient still alive, change dressing'; Nurse:'Either dead patient, or change dressing'; kills patient!
###### 10. Modality / B. Possibility / 8. Conditionals / d. Non-truthfunction conditionals
 14271 Non-truth-functionalist say 'If A,B' is false if A is T and B is F, but deny that is always true for TT,FT and FF
 14272 I say "If you touch that wire you'll get a shock"; you don't touch it. How can that make the conditional true?
###### 10. Modality / B. Possibility / 8. Conditionals / e. Supposition conditionals
 14282 On the supposition view, believe if A,B to the extent that A&B is nearly as likely as A
###### 10. Modality / B. Possibility / 8. Conditionals / f. Pragmatics of conditionals
 14278 Truth-functionalists support some conditionals which we assert, but should not actually believe
 14287 Does 'If A,B' say something different in each context, because of the possibiites there?
